Right now the bitmap is defaulted to 160 x 150 pixels. It would be nice to have it automatically crop out the unneeded blank area around the puzzle, but my attempt to do so with existing code was unsuccessful.

Getting the width and height from the puzzle data was added in my most recent commit to make this easier in the future. Perhaps just cropping the image with a new function would be a better solution than trying to do it with the existing drawing function.

The function for opening ROMs uses some pretty terrible code to check if the ROM is the correct file.

At the moment, it loads the whole ROM to a buffer and checks the first few bytes to make sure they are the proper values. This is not good code.

Try to do the following:

1. Get the size of the ROM
2. Get the ROM's header to see if it's valid
3. Check if the first puzzle is valid (via puzzle size or another known value)

I'm not sure if this is a perfect solution, but it should allow for modified ROMs to work (should we ever support ROM hacks)

Add the ability to export the solutions to the puzzles as bitmap images.

Should be easy enough given that the code needed to generate the bitmaps is already done.

Update: This issue will remain open until the following tasks are completed:

• Add the ability to export individual puzzles as images
• Add the ability to export ALL puzzles as images at once
• Automatically rename bulk exported puzzles to their level names
• Upscale exported images to make them easier to view and use
• Add grids to exported images

The puzzles are loaded based on their indices in the ROM like this: 0x92B0 + (0x20 * index). This works fine for the back end as this is how the game loads the needed puzzle, but the front end should reflect how the player selects a puzzle to solve while in-game.

The puzzles are divided into levels in the game (seen here), so it would make sense for the front end to have the ability to select based on the level name (i.e. Easy 2-B).

It shouldn't be too difficult to convert the puzzle index to its level name, but this will require modifying the UI to allow selecting a puzzle this way. Consider this a stretch goal for later on in the project.
